How to set the line spacing in a JtextPane?

由 南笙酒味 提交于 2019-12-29 08:15:35
问题 First of all, i set the JTextPane like this: HTMLEditorKit editorKit = new HTMLEditorKit(); HTMLDocument document = (HTMLDocument) editorKit.createDefaultDocument(); JTextPane textPane = new JTextPane(); textPane.setContentType("text/html"); textPane.setDocument(document); and i want to set the line spacing in the JtextPane , this is my idea,but it can't work: SimpleAttributeSet aSet = new SimpleAttributeSet(); StyleConstants.setLineSpacing(aSet, 50); textPane.setParagraphAttributes(aSet,

Grouping points that represent lines

由 一世执手 提交于 2019-12-29 05:35:14
问题 I am looking for an Algorithm that is able to solve this problem. The problem: I have the following set points: I want to group the points that represents a line (with some epsilon) in one group. So, the optimal output will be something like: Some notes: The point belong to one and only line. If the point can be belong to two lines, it should belong to the strongest. A line is considered stronger that another when it has more belonging points. The algorithm should not cover all points because

python 利用pyttsx3文字转语音

# -*- coding: utf-8 -*- import pyttsx3 f = open("all.txt",'r') line = f.readline() engine = pyttsx3.init() while line: line = f.readline() print(line, end = '') engine.say(line) engine.runAndWait() f.close() 安装 pip install pyttsx3 语音引擎工厂 类似于设计模式中的“工厂模式”，pyttsx3通过初始化来获取语音引擎。当我们第一次调用init操作的时候，会返回一个pyttsx3的engine对象，再次调用的时候，如果存在engine对象实例，就会使用现有的，否则再重新创建一个。 pyttsx.init([driverName : string, debug : bool]) → pyttsx.Engine 从方法声明上来看，第一个参数指定的是语音驱动的名称，这个在底层适合操作系统密切相关的。如下： 1.drivename： 由pyttsx3.driver模块根据操作系统类型来调用，默认使用当前操作系统可以使用的最好的驱动 sapi5 - SAPI5 on Windows nsss - NSSpeechSynthesizer on Mac OS X

Find a tangent point on circle?

问题 Given a line with first end point P(x1,y1) another end point is unknown, intersect with a circle that located at origin with radius R at only one point(tangent) T(x2,y2). Anyone know how to get the point T? Thanks in advance! 回答1: Given a line with first end point P(x1,y1) another end point is unknown, intersect with a circle that located at origin with radius R at only one point(tangent) T(x2,y2).

Algorithm for drawing a 4-connected line

由 老子叫甜甜 提交于 2019-12-28 05:54:12
问题 I'm looking for an algorithm (coded in Java would be nice, but anything clear enough to translate to Java is fine) to draw a 4-connected line. It seems that Bresenham's algorithm is the most widely used, but all the understandable implementations I've found are 8-connected. OpenCV's cvline function apparently has a 4-connected version, but the source code is, to me, as a mediocre and nearly C-illiterate programmer, impenetrable. Various other searches have turned up nothing. Thanks for any

How do cache lines work?

由 南笙酒味 提交于 2019-12-28 03:15:11
问题 I understand that the processor brings data into the cache via cache lines, which - for instance, on my Atom processor - brings in about 64 bytes at a time, whatever the size of the actual data being read. My question is: Imagine that you need to read one byte from memory, which 64 bytes will be brought into the cache? The two possibilities I can see is that, either the 64 bytes start at the closest 64 bytes boundary below the byte of interest, or the 64 bytes are spread around the byte in

（1） open('00.fig') %打开图片 （2） lh=findall(gca,'type','line')%显示图片所有信息 （3） 打开lh 可以点击查看数据 （4） xc = get(lh, 'xdata') 获取所需要的x轴数据，y轴同理 总结： (1)open('00.fig') %打开图片; (2)lh=findall(gca,'type','line')%显示图片所有信息 (3)xc = get(lh, 'xdata') 获取所需要的x轴数据，y轴同理 来源： CSDN 作者： 小树0310 链接： https://blog.csdn.net/qq_24463801/article/details/103709509
